Abstract:
A method for making a pigment dispersion can include dispersing pigment particles in an aqueous liquid medium to form a dispersion, adding a first monomer to form a dispersive coating on the pigment particles, adding a second monomer to the dispersion, and forming a polymer coating on the surface of the pigment particles by polymerizing the second monomer with the first monomer, wherein the polymer coating includes at least one urethane linkage or urea linkage.
